By the way, test_pool_alloc.cpp is crached - g++ 2.95.3, glibc 2.1.1, with or
without STLport. For example, compiled without STLport:

$uname -sr
Linux 2.2.16
$g++ -o test_pool_alloc test_pool_alloc.cpp
zsh: segmentation fault ./test_pool_alloc
$gdb ./test_pool_alloc

Is it my mistake, or something else?
